## Title
Dry wall extrusion grille

## Abstract

A dry wall extrusion grille comprising a frame, a liner bar grille, sheet rock screws, pre-perforated through holes, indented slots, and a flexible edge.

## Background
FIELD OF THE INVENTION
The present invention relates to a dry wall extrusion grille comprising a frame, a liner bar grille, sheet rock screws, pre-perforated through holes, indented slots, and a flexible edge.
BACKGROUND OF THE INVENTION
U.S. Pat. No. 5,082,083 relates to a structure wall mounted speaker assembly. The woofer of the speaker is mounted in the assembly wall frame and the tweeter is both mounted in and self-contained within the assembly wall frame. The installation requires only that a circular opening be cut in the wall to enable the rear portion of the woofer to extend through the dry wall or sheetrock and two simple holes drilled in the wall to accommodate the support bolts to retain the wall mounted speaker assembly on the wall.
U.S. Pat. No. 7,140,960 relates to duct systems, registers and ductwork components used with floor or ceiling registers employed in warm air heating, ventilating and air conditioning systems, and improvements for mounting and installing components of the duct system, including register boots, mud rings and register grilles, in the walls, floors or ceilings of buildings components, mud ring, register grille and wall, floor or ceiling opening, which reduces costs.
U.S. Pat. No. 7,771,259 relates to a flush mounted frame for an access panel or register. The frame is mounted to a wall, ceiling or floor surface, is made by joining linear frame sections each providing interconnected elements formed by an extrusion process. A first planar element is spaced apart from a second planar element and positioned for abutting a common surface. A first channel element is formed between the first and second planar elements. A third planar element is positioned normal to the first and second planar elements and terminates with a rib directed toward the first planar element. When mounted onto studs in a building structure, wall putty or mud may be placed into a space between the wall panels and the third planar element, the mud is captured in place forming a smooth interface between the frame assembly and the surrounding wall surfaces.
SUMMARY OF THE INVENTION
The present invention relates to a dry wall extrusion grille.
The dry wall extrusion grille comprises a frame, a liner bar grille, sheet rock screws, pre-perforated through holes, indented slots, a flexible edge.
It is an object of the present invention for the indented slots to capture joint compound or plaster.
It is an object of the present invention for the flexible edge to be used for fastening to a wall or ceiling with pre-perforated through holes.
It is an object of the present invention for a common sheet rock screw to be threaded into the wall material.
It is an object of the present invention for the frame to be constructed of four mitered pieces. It is an object of the present invention for the four mitered pieces to be welded together.
It is an object of the present invention for the frame to be installed with a sheet rock screw before plaster or a joint compound is applied.
It is an object of the present invention for the dry wall extrusion grille to be installed to a wall with four sheet rock screws.
It is an object of the present invention for the extrusion grille to have pre-perforated mounting through holes providing many mounting options to address multiple field conditions.
It is an object of the present invention for the extrusion grille to be a fully welded construction that provides exceptional strength for mounting in both walls and ceilings
It is an object of the present invention for the extrusion grille to have multiple, pre-punched mounting holes for fastening in a wide range of wall conditions and materials
It is an object of the present invention for the extrusion grille to have multiple, pre-punched mounting holes for attachment to underlying studs (support beams) for a wide range of center to centers.
It is an object of the present invention for the extrusion grille to have pre-punched holes accurately sized for standard wall board/sheet rock screws so no special hardware or tools are required.
It is an object of the present invention for the extrusion grille to have multiple indented slots along the mounting flange to provide capture points for joint compound or plaster.
It is an object of the present for the extrusion grille to comprise flexible mounting flange that fasten the grille to uneven wall surfaces.
It is an object of the present invention for the inside of the extrusion grille frame to extend 3⁄4′′ deep into the opening so that the extrusion grille is installed in a wall board or plaster ranging from about 1⁄4′′ thru about 3⁄4′′ thick.
It is an object of the present invention for the extrusion grille to allow an installer to cut a very rough hole in a wall and slip the extrusion grille frame into the opening. With the design of the present invention there is no routing or recessed cut that is necessary. With the design of the present invention there is no blocking or added wood necessary for attachment to wall.
It is an object of the present invention for the extrusion grille to provide exceptional strength using aluminum material—thus enabling safe use in ceiling applications.
It is an object of the present invention for the extrusion grille to be used with a fixed core (core welded directly to the frame or removable core for access to either controls or filtration behind the grille).
It is an object of the present invention for the extrusion grille to be used specifically for linear bar grilles, and not used with perforated grilles or registers.
It is an object of the present invention for the extrusion grille to be mounted, so that the entire frame and grille are flush to the wall providing a seamless installation—which makes field painting much easier—also makes future cleaning of the grille simpler as can be done with simply the wipe of a rag
It is an object of the present invention for the extrusion grille to be mounted in only one way, so that it cannot be installed backward.
It is an object of the present invention for the extrusion grille to require four pieces for construction, providing faster assembly and lower cost.
It is an object of the present invention for the extrusion grille to have a special angled edge that provides a step for a standard spackle knife to rest when a plaster or joint compound is being applied. This creates a crisp, clean line set up for the application of the final skim coat of plaster (joint compound).

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows the frame 10 comprising four mitered pieces 12, 14, 16 and 18, which are welded at 20, 22, 24, and 26. FIG. 2 shows the bottom view of frame 10 of FIG. 1.
FIGS. 3 and 4 show the extrusion grille 30, which comprises a linear bar grille 32. The extrusion grille 30 has an aluminum profile 34, a flexible mounting flange 36 that is used for fastening to a wall or ceiling with perforated through holes 40. The extrusion grille 30 further comprises indented slots 38 used to capture joint compound or plaster 42.
Extrusion grille 30 further comprises a special angled edge 44 to create a step for a spackling knife to use as a straight edge. A common sheet rock screw 46 is threaded into the wall material.
FIG. 5 shows the extrusion grille 30 having the linear bar grille, a standard sheet rock screw 46, and pre-perforated mounting through holes that provide many mounting options to address multiple field conditions.
FIG. 6 shows the extrusion grille 30 installed after the plaster or joint compound is applied. The frame 10 is installed with the sheet rock screw 46 before plaster or joint compound is applied.
